  //  Santa needs help figuring out which strings in his text file are naughty or nice.
  //
  //    A nice string is one with all of the following properties:
  //
  //    It contains at least three vowels (aeiou only), like aei, xazegov, or aeiouaeiouaeiou.
  //  It contains at least one letter that appears twice in a row, like xx, abcdde (dd), or aabbccdd (aa, bb, cc, or dd).
  //    It does not contain the strings ab, cd, pq, or xy, even if they are part of one of the other requirements.
  //    For example:
  //
  //    ugknbfddgicrmopn is nice because it has at least three vowels (u...i...o...), a double letter (...dd...), and none of the disallowed substrings.
  //  aaa is nice because it has at least three vowels and a double letter, even though the letters used by different rules overlap.
  //    jchzalrnumimnmhp is naughty because it has no double letter.
  //    haegwjzuvuyypxyu is naughty because it contains the string xy.
  //    dvszwmarrgswjxmb is naughty because it contains only one vowel.
  //    How many strings are nice?
